Jason,
Those instructions are correct. Over the years we have changed the routing around to suit different schools of thought. We have also changed the routing as different lines have become available.
We finally came to the conclusion it doesn't matter which way you run the lines (as long as
oil can flow). Some people want to cool their
oil first; some people want to filter before the
oil cooler so if the engine blows up then they don't loose the cooler too because the filter supposedly catches all the junk...
Well, after a lot of thought, we figured there were other things that were much more important...like routing the lines in way so that they were as far as possible away from bad things--like steering shafts, hot headers, etc.
Also, lately, we are using some really, really cool fittings on the end of our hoses. They are double swivel fittings. The hose can swivel on the fitting and the fitting can also swivel on the block, oil cooler, filter mount--whatever. This is TREMENDOUSLY important! If a line is not indexed properly between both ends then there will be a little twist on the line. The line (or the fitting it is attached to) will eventually fatigue and crack as they are subjected to heat cycles and pretty intense vibration. The double swivel eliminates that headache.
